The move is part of the company's recent reorganisation into two divisions – Northern and Southern – and Heidelberg said the number would "simplify the process of reaching the correct customer service area".
"Customers' time is important and providing them with easy and quick access to our comprehensive spread of services makes sense," said George Clarke, managing director.
"While Heidelberg remains the largest and most comprehensive supplier of graphic arts equipment in the UK, we are always looking to enhance our reputation for being the easiest to deal with and this new phone line fits into that strategy."
The new number, 0844 892 2010, will be available from Monday 6 April.
